The Mandela Catalogue is an analog horror web series created by Alex Kister and first released on YouTube in 2021, built around distorted VHS-style footage and beings known as alternates. Its mix of uncanny visuals and deadpan dialogue helped it grow a large online fandom, with short clips, edits and reaction videos spreading widely on YouTube and TikTok. Brief, out-of-context lines like this friendly hey became popular because they contrast sharply with the series' tense atmosphere, making them easy to reuse as greetings, jokes or ironic introductions in fan content.
